Parameter Settings
The EX600 has parameter settings for the system, unit and each unit’s channel, which can be set through
PLC or hand-held terminal. There are no priorities in setting the parameters. The unit will use the most
recent setting.

1 Hold/Clear
setting
method
Select setting method of output state during communication fault or during
communication idle state, either with the unit setting switches or by using a HT When
using a HT, each channel’s output state can be set to Hold/Clear/Force ON. When
using setting switches, the entire system output state can be set.

1
Power supply
voltage monitor
(control/input)
When power supply voltage for control/input goes above 26 V or falls below 21
V a diagnostic error will be generated.
2
Power supply
voltage monitor
(output )
When power supply voltage for output goes above 26 V or falls below 20 V a
diagnostic error will be generated.
3
Short circuit
detection
If a short circuit or over current occurs when the valve output is ON a diagnostic
error will be generated.
4
Restart after short
circuit
The short circuit detection diagnostic can be set to automatic or manual reset.
5
Open circuit
detection
If an open circuit is detected during valve output OFF, a diagnostic error will be
generated. This setting can be made for each channel.
6
Output setting
during
communication
fault
When there is a communication fault, each channel’s valve output can be set to
Hold, Clear or Force ON setting. This function will only be activated when the
Hold/Clear setting method at the system configuration is set to Handheld.
7
Output setting
during
communication
idle
When communication is idle, each channel’s valve output can be set to Hold,
Clear or Force ON setting. This function will only be activated when Hold/Clear
setting method at the system configuration is set to Handheld.
8
Channel ON/OFF
counter
The number of times the valve is ON/OFF is recorded for each channel.
There is a set value for each channel and a diagnostic error is generated when
the set value is reached.
Recording the ON/OFF number is done in 30 s intervals (30 s per channel) from
CH0 to the channels, which have valve outputs.
If the power supply for control and input is turned OFF, the last recorded value
for each channel will become valid.
